Set storage location of MongoDB installed on AWS EC2 Instance to EBS storage And How do I recover It after instance is stopped terminated

Question

I am new to AWS. I have created and Instance and installed MongoDB on It. But I learned from EC2 docs that the data stored on EC2 machines are destroyed once they stop or are terminated. So I have to use EBS for the data storage.

On the 4th step of creating EC2-Instance, I selected the volume

But I don't know how to use it. Is it automatically used by EC2-Instance to store the data in it or do we have to manually do it? I know that for changing the database storage we have to change the file named mongod.conf and modify the dbpath there but I don't know what path to give there. and after that also if I destroyed that instance when I will get the EBS storage back. Thanks in advance for the help.

In your screenshot, the EBS volume is the root volume for the instance. So unless you add other volumes to the instance, everything persisted on disk on that instance is going to be stored on the EBS volume. You can pick any location to store your database.
